Update the Praefect scenario
It now uses a multi-node Gitaly Cluster (plus another Gitaly-standalone storage).
Depends on https://gitlab.com/gitlab-org/gitlab/-/merge_requests/45100, which allows the repository move test to check Praefect logs in a separate container instead of the same container as the GitLab instance.
